Chapter 47: Badly

Chapter 47: Bad Up
Arthur looked at Faraday who was standing right in front of him, feeling the other party’s kind and gentle attitude, with that déjà vu face.

Arthur was silent for a while, and suddenly felt that maybe it was better to see him in the textbook.

Even though Arthur thought he was pretty good at physics and his memory was in the better range.

But what if, what if he memorized the wrong theorem then he wouldn’t be immortalized for years to come?

Faraday saw that Arthur did not speak for a long time and thought that his sudden arrival had attracted too much attention from the audience, thus frightening the science-loving Scotland Yard police officer.

At the Royal Society, Faraday often came into contact with such scientists who disliked attention.

As such, he took it for granted that Arthur would be categorized as one of their kind.

Embarrassed, Faraday owed himself an apology and said, ”Mr. Officer, I did not mean to interrupt the discussion between you and your friend.

But I think this memorization method you mentioned just now seems to be really suitable for helping students who are new to the field of electricity.

If you’re too embarrassed to share it in public, we can wait until after the lecture is over to slowly exchange ideas.”

Just after Faraday’s words, Arthur had not yet replied, but Elder, who was sitting on the side, was not happy about it.

This kid found that the focus of the ladies’ eyes were converging on the three of them, and Elder, whose hormones were soaring to the limit, snapped and stood up, rushing at Faraday to open his mouth.

“Mr. Faraday, this friend of mine is shy by nature and not good at talking. Just ask me if you have any questions.”

Seeing that Elder was actually willing to volunteer, Faraday happily shook his hand, “Then, may I ask you, what exactly happened with that right hand just now?”

“This is simple. This …… right hand well …… is …… the right hand …… ugh… …”

Perhaps it was because he stood up too violently, so that the blood supply in Elder’s body could not keep up with the oxygen, and his mind went blank, not to mention repeating the knowledge that Arthur had taught him, he could not even say a complete sentence.

Young Master Elder stammered for half a day, and somehow suddenly had a flash of light in his head.

He grabbed Faraday’s right hand and put it in front of his eyes, studied it carefully for half a day, and only then spoke slowly.

“Uh …… Mr. Faraday, your right hand wisdom line ……”

Elder this word out, the venue immediately burst out a burst of bursts of laughter, the air is filled with a cheerful atmosphere everywhere.

The reserved ladies picked up their fans to cover their mouths, and their eyes narrowed into a line with laughter.

As for the men, they weren’t so preoccupied, they couldn’t catch their breath from laughing, each covering their stomachs and not being able to straighten their backs.

The gentleman who sat behind Arthur, who graduated from Cambridge, even laughed while slapping the back of his chair, and he shouted in a broken voice.

“No …… right. They …… they Oxford education is like this.”

Seeing this, Arthur couldn’t help but cover his face with one hand, “Elder, if you don’t know, you don’t know, what’s the point of showing off?”

Elder’s face turned white and his heart was a sweaty head, he cursed in a low voice, “Arthur, Arthur! You fucking save me!”

Things had come to this point, Arthur couldn’t come out even if he didn’t want to.

He stood up and opened his mouth to explain, “Mr. Faraday, I ……”

Faraday was also a bit overwhelmed by this scene of antics that Elder had gotten out of him, and when he saw Arthur stand up, his first reaction was actually to hesitantly ask, “You wouldn’t want to help me look at the fate line again, would you?”

Before Arthur could say anything, Elder, who was eager to get rid of the embarrassment, snatched his mouth and said, “Mr. Faraday, there is no need to trouble Arthur with this kind of small matter, I’ve already finished reading it all for you, and your destiny line is also very good.”

This time, the laughter in the meeting hall could almost be used for a concert.

Hearing this, the always good-tempered Arthur finally couldn’t help glaring at Elder and muttering in a low voice at him. “What business do you have here? Don’t shut up yet!”

Elder hurriedly stopped his mouth, and he also knew that if he said two more words, his reputation in the Royal Society Lecture venue would be all but ruined from now on.

Arthur took a deep breath and quickly adjusted his emotions.

He spoke, “Mr. Faraday, the right hand is what I use to determine the direction of electricity. Of course, you used a coil in your second experiment, so it can also be used ……”

Hearing this, Faraday nodded his head repeatedly and said, “That’s right, the coil can be judged by Ampere’s rule, the right-handed spiral rule. But that right hand rule you just mentioned seems to be different from the right hand spiral rule.”

When Arthur heard this, although his face still maintained the inherent calmness and composure of a Scotland Yard policeman, the Red Devil beside him had already begun to laugh uncontrollably.

“Arthur, what’s the matter with you? Look at your neck, the sweat is coming down. Don’t you know the right hand spiral rule? That was formulated by the Frenchman Andre Ampere in 1820. If you don’t know, I can teach you. One soul for a fair and cheap price.”

But though Agareth saw Arthur sweating, he had obviously guessed Arthur wrong; it wasn’t that Arthur didn’t know the right-handed helix rule, but what amazed him was this – that Ampère had actually come up with it?
Arthur pondered for a while and spoke cautiously, “I was also inspired by Ampere’s rule, so I came up with the method of using the right and left hands to make judgments.

The right hand rule is judged by making the thumb perpendicular to the remaining four fingers and all in a plane with the palm.

At this point, place the right hand in a magnetic field so that the magnetic inductance passes perpendicularly through the palm of the hand, with the thumb pointing in the direction of the conductor’s motion, then the direction that the remaining four fingers point is the direction of the induced current.”

Faraday sniffed, immediately stretched out his fingers and gestured to himself, not long, his tightly frowning eyebrows suddenly stretched out.

He laughed joyfully, “It’s really like this!”

Once Faraday said this, the laughter of the ladies and gentlemen present faded, and they all stretched out their right hands to gesture at each other.

It didn’t take long before an uproar could be heard ringing through the venue.

“What a genius summary.”

“It’s like what Mr. Faraday said, it’s really good for beginners to use for memorization.”

“Mr. Officer, then what about the left-handed rule?”

Faraday, hearing that the audience had already started to ask for him, didn’t say anything and just looked at Arthur with a smile.

Arthur also understood the meaning in Faraday’s eyes, and he held out his own left hand to demonstrate, “The left hand rule is used in much the same way as the right hand, with the difference that it is used to judge force rather than current.

Ladies and gentlemen, stretch out your left hand so that the thumb is perpendicular to the other four fingers, so that the lines of magnetic induction flow in from the palm of your hand, with the four fingers pointing in the direction of the current, and then the thumb is pointing in the direction of the amperometric force, i.e., the direction of the force of the energized wire in the magnetic field.

If the moving charge is positive, the pointing of the thumb at this point can also be expressed as the direction of the Lorentz force, while if the charge is negative then the opposite direction of the thumb pointing is the direction of the Lorentz force.”

Arthur finished the paragraph with a slight sigh of relief.

Memorize right and wrong he already does not matter, anyway, like Faraday this kind of master-level scientists if he found that he was wrong, but also will certainly be corrected, in order to help Elder get out of the way, today he is a kind of give up.

Just as he was about to sit down, Arthur suddenly realized that the atmosphere in the venue was not quite right.

The ladies and gentlemen present neither took out their hands to gesticulate as they did just now, nor did they burst into laughter, but they all stared at him blankly.

Just when Arthur was puzzled, Faraday opened his mouth.

With an apologetic face, he inquired to Arthur, “Please forgive my ignorance, can I take the liberty to ask you, what is the Lorentz force?”

When Arthur heard this, his pupils shrunk slightly, and in his heart he said, “Bad, something big has happened.”
